IMPROVEMENT IN RULERS.

Specification forming part of Letters Patent No. 159.294, dated February2, 1875; application tiled November 30, 1874.

To all whom Iit may concern:

Be it known that We, HENRY BELOHER and THOMAS H. BELCHER, both of thevillage of Irvington, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Rulers; and We dohereby declare that the following is a full, clear, and exactdescription thereof, Which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain improvements in the manufacture ofrulers; and consists in inserting in each edge thereof thin strips ofmetal of dicerent forms, as will be hereinafter more fully set forth.

One edge of the ruler is beveled in the ordinary manner, and a thinstrip of metal, a, is inserted in a groove formed diagonally in the edgethereof, which is so cut that there is formed a slnall under lipsomewhat back from the true edge of the rule, but making a supy l portfor the piece of sharpened metal a, which is secured therein by means ofrivets, after which it is finished by being sharpened in the usualmanner, forming a tine smooth edge for cutting paper. The opposite edgeis nished with a convex and concave surface, and is also provided with athin strip of metal, b, also inserted in a groove made parallel with thesides of the ruler in the convex portion of the edge thereof, andprojecting outward a trifle less than one-eighth of an inch. This pieceof metal is inserted parallel to the upper and lower surface of therule, forming a smooth metallic edge for ruling. The sharpened edgedmetal A is placed into the Wooden center in a diagonal direction, sothat its fine edge may rest upon the same surface as the flat side ofthe ruler.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent of the United States, is-

A combination ruler and paper-cutter, constructed with the sharpenedmetal paper-cutter set at an angle into Wooden center, and so arrangedthat its edge rests upon the saine plane as the corresponding flatsurface of its wooden center, as herein described.

In testimony that We claim the foregoing as our own invention We affixhereto our signatures in presence of two Witnesses.
